i have a Peavey 1516 bass cab as of now, which is a 15in. speaker and 2 8in. speakers. I have been trying to find another bass cab that is similar to this design, but i've had no luck. I found one made by CARVIN, but it was a combo amp, not a seperate cab. I am interested in finding a second cab of this design because i read that when 2 similar cabs are placed next to or on top of eachother, they seem to be louder and an few extra decibels are gained in this way. please add a post if u know any company that makes cabs similar to this design.
